Thanks, Peter.  It's fine on 0.9.29 as well.  I just spent some time
going over its .configure script and made a few adjustments (it's really
geared to glibc) so the different components link against libpthread in
the Makefile.  Same bad result using the uClibc NPTL branch, though. 
Socket read() by dbus-daemon returns -1 with errno = E2BIG.  I no longer
think the problem is with pthreads per se since neither the daemon nor
dbus-monitor create any.  Not really sure what to think now.
